摘要： PROBLEM TO BE SOLVED: To produce a ceramic product which is safe and physically stable and from which any heavy metal or the like, is not eluted by melting ash in a waste material, crystallizing the molten ash to form a crystallized material, mixing the crystallized material, a plastic raw material and a nonplastic raw material together in a specified mixing ratio, forming the resulting mixture into a formed body, drying the formed body and firing the dried body at a specified temperature. SOLUTION: The ash in a waste material is fused at 1,300-1,500 deg.C then cooled to form a glassy material, and the glassy material is reheated to almost completely crystallize the glassy material thereby obtaining a crystallized material containing at least either anorthite crystals or β-wollastonite crystals. The 40-70 wt.% of the crystallized material, 10-50 wt.% of a plastic raw material for providing plasticity and viscosity and the remainder of a nonplastic raw material for adjusting mechanical strength, rigidity and toughness are ground and mixed, then an adequate amount of water is added to the resulting mixture to knead the mixture, and the kneaded mixture is formed, dried and fired at 1,000-1,200 deg.C to produce a ceramic product. Wherein as the plastic raw material, a clay mineral such as kibushi clay (produced in Japan) is used and as the nonplastic raw material, a rock mineral such as feldspar is used.

摘要： PROBLEM TO BE SOLVED: To provide a method for forming waste molten slag into aggregate by which the molten slag made from the waste is formed more economically into a solidified material easy to reutilize and having strength. SOLUTION: The waste 15 is gasified in a fluidized-bed gasification furnace 1, the dust in the gas is melted in a melting furnace 5, and the formed molten slag 17 is formed into aggregate. In this method, the molten slag is solidified in the fluidizing medium of the gasification furnace, and the medium-mixed and solidified slag is calcined in a rotary kiln. Otherwise, the molten slag is solidified in the fine solidified slag generated when the waste molten slag is formed into aggregate, and the slag mixed with fine solidified slag is calcined in the rotary kiln. Alternately, the molten slag is allowed to flow in the kiln while keeping molten state, the fluidization medium or the fine solidified slag is blown against the molten slag along with a pressurized gas, the mixture is covered with molten slag and cooled, and the medium-mixed slag is calcined in the kiln.

摘要： PROBLEM TO BE SOLVED: To provide a method for recovering solvent by which the supply of an inert gas from the outside is decreased, energy loss is minimized, and the load on the adsorptive operation side is also lowered. SOLUTION: Three or more adsorption towers are set in parallel, each tower is repeatedly subjected to one stage among a gaseous solvent adsorbing stage (a), an adsorption, bed regenerating stage (b) consisting of a heating stage, dry desorbing stage and cooling stage and a stage (c) for recovering the desorbed gas from the regenerating stage and adsorbing the gaseous solvent remaining after cooling, and the gaseous solvent is continuously adsorbed. In this case, the clarified gas discharged from the stage (c) is repeatedly reused as the dry-desorbing and cooling gas in the stage (b), and an inert gas is used as the dry-desorbing and cooling gas. An inert gas such as nitrogen and carbon dioxide is used as the desorbing and cooling gas.

CONSTITUTION:After a radioactive waste liq. or a condensate is filtered, a shell vent valve 5 and an air scrubbing valve 9 are opened to carry out scrubbing. The valve 9 is closed, and a water inlet valve 8 is opened to fill a liq. The valves 5 and 8 are then closed, a compressed air valve 2 and a dome drain valve 3 are opened, and dome draining is carried out. The valve 3 is then closed, and the dome is pressurized by compressed air. A backwashing discharge valve 10 is then opened, and the hollow yarn membrane is bumped to release the suspended matter deposited on the membrane. A valve 6 is then opened to introduce compressed air, and the liq. contg. the suspended matter is discharged. Liq. filling is again carried out, and scrubbing, dome pressurizing, bumping, and discharging are successively carried out.
